Screw SCHROFF M4×12 mm cylindrical head, pack of 100

SCHROFF cylindrical head screw M4×12 mm in a pack of 100 is a metric machine screw designed for general fastening tasks in electronics enclosures, server racks and computer hardware assemblies. The M4 thread and 12 mm length make it suitable for joining panels, brackets and modules where a compact M4 fastener is required. Supplied as a bulk pack of 100 screws, this product supports repeated assembly and maintenance operations in workshops and production environments.

Advantages

The cylindrical head profile provides a low-profile bearing surface and consistent torque distribution when securing components. The M4×12 mm dimensions match common metric mounting patterns used in electronic chassis and IT racks, enabling straightforward interchangeability with existing fasteners. Packaging in a pack of 100 reduces the need for frequent reordering and supports efficient inventory management for repetitive assembly tasks.

Suitable for

• Fastening panels and covers in electronic enclosures
• Mounting brackets and small modules in server racks
• General assembly and maintenance of computer hardware
• Workshop and production line bulk fastening needs

Key specifications

• Thread size: M4
• Length: 12 mm
• Head type: cylindrical (round/low-profile bearing surface)
• Quantity: 100 pieces per pack
• Intended application: metric machine screw for metal/plastic assemblies

How to use

Select a matching M4 tapped hole or use an appropriate M4 nut when assembling parts. Use the correct driver or hex key that fits the screw head to apply controlled torque and avoid over-tightening. For repeatable results in production, verify thread engagement and clamp length so that the fastener secures the parts without bottoming out or leaving insufficient thread engagement. When fastening into thin panels, consider adding a washer if required to spread load and prevent deformation.

Usage recommendations

Store screws in a dry environment to prevent corrosion if not supplied with a protective coating. Use the recommended torque values for M4 fasteners in the specific material being fastened, and inspect assemblies periodically for loosening in high-vibration applications.
